Just had this brought to my attention. I've only skimmed through the video, but it looks as if they've managed to get the M4 MacBook Pro early. Not out of the question considering that it should already be in mass production at this point. Hopefully nobody beats me to posting this here.
I recently bought a 16" M3 Max Base Model (14 core CPU, 30 core GPU)...
I was planning to upgrade from my M1 Max (10 core CPU, 32 core GPU) but I haven't opened the new computer yet as I've just been realizing that my current M1 Max is totally fine for my needs. I really didn't need to upgrade...
